I am working on TRAXE version 2 which is a chiptune tracker with 3 channels and it will be used in combination with the TIMID soundchip. I want it to have calculator generated sound as well for those who don't have the soundchip. Send me a pm and maybe you can help me with that.
Erm, I didn't understand everything in that post due to the presence of too precise English words 
What is a "chiptune tracker" exactly ?
Is a soundchip external hardware (external from the point of vue of the calculator) ?
Not bad. You should consider adding a noise channel. I did it in Bad Apple by reading from the r register, but having a properly random sequence of bits should sound better.
A noise channel ? That would be a channel with random noise on it ??
It's basically an arduino which runs a SID soundchip emulator.

Tile based graphics. Very slow communication with the video generator though.

How about a text adventure bot?

This is correct. Try taking the audio directly from pin 9.

Did you reset the soundchip after you plugged it in? Is your cable too long by chance? Did you connect arduino pin 10 to ground?

Just change that to TESTVAR. I forgot to change it back

SPI is really straightforward.
Clock line is normally high.
Set up data. Wait for a bit to let the line settle.
Pull down clock line. Wait for a bit to let the line settle.
Release clock line. (Normally high again)
Do this for all 8 bits and you have sent a byte.
But since the nspire has a much nicer cpu than the 84+ CSE you might be able to play sound generated in software. Even the CSE can do it.

Traxe 2.0 is being worked on! It will use the TIMID soundchip to generate more complex sounds. You can have up to 3 channels of sound with various waveforms.

If you can write an SPI routine for the nspire you could interface with my soundchip. I recently worked on that project. SPI is quite straightforward. You shift out bytes least significant bit first on the clocks falling edge. You only need two signal lines.

By using a simple audio filter you can filter out anything above a certain frequency.

Do you want physical keys?

You can use pwm or you could use external hardware like a digital to analog converter with a 2 wire interface.
